I own a LOOK KG381 and can get a good deal on a KG461 as a second bike but I don't have the opportunity to test ride one. I wonder if there is anyone out there who has ridden the 461 and 381 and can give me the differences as far as riding characteristics are concerened. I am also looking at a Giant TCR which I once had and loved but the LOOK is tempting especially for the price. Thanks in advance!
